Cooling system package

ABSTRACT

A cooling system package is disclosed comprising a first container of antifreeze liquid and a separate second container of stop leak material, said second container comprising a body of flexible sheet material having a center portion provided with a central aperture and two envelopes spaced apart on opposite sides of said aperture, said envelopes containing said stop leak material and in sufficient quantity for admixture with the amount of antifreeze liquid in said first container, and means for affixing said second container to the top of said first container to maintain them together during shipment and storage so that they may be admixed in a cooling system at the point of use.

Fisher ABSTRACT: A cooling system package is disclosed comprising a first container of antifreeze liquid and a separate second container of stop leak material, said second container comprising a body of flexible sheet material having a center portion provided with a central aperture and two envelopes spaced apart on opposite sides of said aperture, said envelopes containing said stop leak material and in sufficient quantity for admixture with the amount of antifreeze liquid in said first container, and means for affixing said second container to the top of said first container to maintain them together during shipment and storage so that they may be admixed in a cooling system at the point of use.

COOLING SYSTEM PACKAGE My invention relates to packaging of cooling system preparations beneficially added to a cooling system such as that for an internal combustion engine.

The principal object of my invention is the provision of a cooling system package which separately contains predetermined quantities of two cooling system preparations and maintains them together during shipment and storage so that they may be admixed in a cooling system at the point of use.

The foregoing object of my invention and the advantages thereof will become apparent during the course of the following description, taken in conjunction with the accompanying drawings, in which:

FIGS. 1 and 4 are, respectively, top plan and perspective views of a cooling system package embodying my invention;

FIG. 2 and 3 are, respectively, front and end elevational views of a part of said cooling system package; and

FIG. 5 is a vertical sectional view showing two such cooling system packages in stacked relationship.

Referring to the drawings in greater detail, designates said cooling system package which comprises a container 12 of antifreeze liquid 14 such as ethylene glycol having affixed to the top thereof another separate container 16 of stop leak material such as ginger root flour and soluble oil. (See my prior US. Pat. Re Nos. 24,094 and 2,935,189.) The container 16 comprises a body of flexible sheet material consisting of two sheets pressed together in face to face relationship having a center portion provided with a central aperture 19 and two envelopes 20 spaced apart on opposite sides of the aperture 19 each containing said stop leak material 18. The two envelopes on the container 16 are required to provide sufficient stop leak material for admixture with the amount of antifreeze liquid in the container 12. The container 16 is affixed to the top of the container 12 by forcing the aperture 19 beneath the larger diameter fill cap 22, the smaller diameter neck for the fill cap 22 being of the same diameter as that of the aperture 19. The container 16 is thus retained in the depression in the top of the container 12 without interfering with stacking of the container 12 on top of each other as shown in FIG. 5.

it will thus be seen that there has been provided by my invention a cooling system package in which the object hereinabove set forth together with many thoroughly practical advantages has been successfully achieved. While a preferred embodiment of my invention has been shown and described it is to be understood that variations and changes may be resorted to without departing from the spirit of my invention as defined by the appended claim.

What is claimed is:

1. A cooling system package comprising a first container of antifreeze liquid having a sealed fill cap centrally formed in the top wall thereof and a separate second container of stop leak material, said second container comprising a body of flexible sheet material having a center portion provided with a central aperture therein and having two sealed container envelopes spaced apart on opposite sides of said central aperture, said envelopes entirely enveloping and containing therein said stop leak material and in sufficient quantity for admixture in said cooling system with the amount of antifreeze liquid in said first container, and means for affixing said second container externally of and to the top of said first container including said second container disposed on top and within the confines of the top wall of said first container with said central aperture beneath said fill cap and encircling the neck thereof to maintain the two containers together during shipment and storage so that the contents thereof may be admixed in a cooling system at the point of use.
